Computers (and peripherals)

From Macdiyvers

Power supply is useful as a unit, or can be taken apart for transformer, caps, diodes, and similar. Many have a filtered input connector which is rather valuable. There are usually some LED and switches on the end of wires that plug into header blocks. They also may have CD DVD Floppy Drives see separate discussion. The connecting wires are often useful, sometimes taking the connectors off the mother board makes them more useful. Individual boards may be useful as they are. The mother board is not usually useful for its chips, most are too small and specialized for much use. Crystals may be found, not sure if frequencies are useful. AT-era PC's often had D-connectors of both sexes on ribbon cables and peripherals have matching cables. Some have RTC modules, others have CR2032 lithium batteries. The big BIOS flash/eprom may be recyclable. Certain vintages have nice SRAM chips as cache. SCSI and other smart controllers have serial eeprom's for settings. Old ethernet cards and cables yield 50-ohm coaxial wiring. Loads and loads of screws in the case.
